The advisory is in effect from 11 p.m. Thursday through 10 a.m. Friday in most areas.

Temperatures are expected to fall below freezing a couple hours after the first precipitation falls, National Weather Service officials said. The precipitation won't be significant, but it still could lead to slick spots on roadways, specifically bridges and overpasses.

Below is a regional look at what the National Weather Service expects to happen:

Triad: An inch or less of a snow-sleet mix could accumulate mainly on grassy areas, and ice accumulations are expected to be less than 1/8 inch.

Foothills: The biggest threat is up to a tenth of an inch of freezing rain accumulation. Less than an inch of sleet is expected.

Mountains: As much as two tenths of an inch of freezing rain could fall, possibly causing spotty power outages. Less than an inch of sleet could fall as well.
